The island is popular with many tourists because of its white sand and clear waters. There are tour options that provide meals, which is something you should get if you’re to visit Tortuga Island. It’s isolated, undeveloped, and very pristine. The trip to the island can take an hour and will sometimes be rough depending on the season. You can hike around the island, but most visitors go for some snorkeling just off the coast of the island. Jagged volcanic rock spills into the ocean creating a dramatic contrast against the brown sand, red rocks, and crushed shells.
Playa Hermosa is popular with many expats being 20 minutes away from the Daniel Oduber International Airport. While there is an actual residential community living by the beach, there are still several hotels that offer comfortable accommodations. The gentle waters make it very family friendly for some fun in the water with the kids and a very relaxing snorkeling experience. The best snorkeling spots, however, are a little off the beach and towards the cliff where a small white sand bay hides between the rocks. Underwater will be rocky reefs covered in seaweed surrounding and a large number of blennies and Cortez rainbow wrasses.

La Penca is a small beach on the peninsula separating Playa del Coco and Playa Hermosa on Costa Rica’s Pacific coast. The entry into the water gives you 20 meters of rocky seabed before hitting the sandy area. Large groups of wrasse and damselfish rest near the rocks, where small moray eels sometimes nestle underneath. The left side of the area, towards the cliff, gives more interesting sights. It can be a little bit challenging, but there are many species taking shelter within the rocks. You’ll find butterflyfish, and different species of angelfish. Because of its topography, however, the waters can be quite rough and will be slamming against the rocks. You’ll have to be careful and postpone your snorkeling when you see some waves.
